NAME

       gpiv_trig - triggers a (double Nd_YAGG) laser with a CCD camera.

SYNOPSIS

       gpiv_trig [-h | --help] [-i | --interactive] [-v | --version] [-V | --verbose]

DESCRIPTION

       gpiv_trig  triggers  a  CCD  camera  and  a  (double  Nd_YAGG)  laser  for  Particle Image velocimetry (PIV). The code uses a kernel module
       gpivtrig_rtl from the gpivtrig package that depends on the Real Time Application Interface (RTAI) and  RealtimeLinux.  Trigger  pulses  are
       send  to the parallel port of the PC (/dev/lpt0 or /dev/lpt1; see the configure script of the gpivtrig package) at bins #1 (camera), #2 and
       #3 (first and second laser respectively). The program may be started directly if all modules  have  been  loaded  or  by  the  gpiv_control
       script,	also  included	in  the  gpivtrig package,  which takes care of the loading and unloading of the needed kernel modules. Currently,
       gpiv_trig is tested with RTAI-3.1 and the linux kernel-2.4.27.

       This program uses the TRIG parameters. The command line options are explained below.

Options
       -h | --help
	      On-line help.

       -i | --interactive
	      Prompt for confirmation.
